Sources and production of polonium
A freelance killer would not be able to obtain polonium legally from commercially available products in the amounts used for Litvinenko poisoning, because more than microscopic amounts of polonium can only be produced in state-controlled nuclear reactors.(see also commercial products containing polonium for detail).
Ninety seven percent of the world's legal polonium-210 (210Po) production occurs in Russia in RBMK reactors About 85 grams (450,000 Ci) are produced by Russia annually. According to Sergei Kiriyenko, the head of Russia's state atomic energy agency, RosAtom, all of it goes to U.S. companies through a single authorized supplier. The production of polonium starts from bombardment of bismuth (209Bi) with neutrons at the Ozersk nuclear reactor, near the city of Chelyabinsk in Russia. The product is then transferred to the Avangard Electromechanical Plant in the closed city of Sarov. This of course does not exclude the possibility that the polonium that killed Litvinenko was imported by a licensed commercial distributor, but no oneincluding the Russian governmenthas proposed that this is likely, particularly in regard to the radiation detected on the British Airways passenger jets travelling between Moscow and London. Russian investigators have said they could not identify the source of polonium.
Polonium-210 has a half-life of 138 days and decays to the stable daughter isotope of lead, 206Pb. Therefore the source is reduced to about one sixteenth of its original radioactivity about 18 months after production. By measuring the proportion of polonium and lead in a sample, one can establish the production date of polonium. The analysis of impurities in the polonium (a kind of "finger print") allows to identify the place of production. It is assumed by Litvinenko's wife and his close confidant that British investigators were able to identify the place and time of production of polonium used to poison Litvinenko, but their findings remain unpublished.
Possible motivation for using polonium-210
Philip Walker, professor of physics at the University of Surrey said: "This seems to have been a substance carefully chosen for its ability to be hard to detect in a person who has ingested it." Oleg Gordievsky, the most senior KGB agent ever to defect to Britain, made a similar comment that Litvinenko's assassination was carefully prepared and rehearsed by Russian secret services, but the poisoners were unaware that technology existed to detect traces left by polonium-210: "Did you know that polonium-210 leaves traces? I didnt. And no one did....what they didnt know was that this equipment, this technology exists in the West they didnt know that, and that was where they miscalculated."
Nick Priest, a nuclear scientist and expert on polonium who has worked at most of Russia's nuclear research facilities, says that although the execution of the plot was a "bout of stupidity", the choice of polonium was a "stroke of genius". He says: "the choice of poison was genius in that polonium, carried in a vial in water, can be carried in a pocket through airport screening devices without setting off any alarms", adding, "once administered, the polonium creates symptoms that don't suggest poison for days, allowing time for the perpetrator to make a getaway." Priest asserts that "whoever did it was probably not an expert in radiation protection, so they probably didn't realize how much contamination you can get just by opening the top (of the vial) and closing it again. With the right equipment, you can detect just one count per second".
